Will we know our loved ones in heaven?

There are several indications in Scripture that we will maintain our identity in heaven and, thus, be recognizable to our loved ones (and they to us). For example, Jesus makes it a point in Matthew 22:31-32 that Abraham, Isaac and Jacob were alive and existing as individuals by those names.

In Matthew 17:1-8, Peter, James and John recognized Moses and Elijah. In 1 Thessalonians 2:19-20 Paul expected to recognize in heaven the Thessalonian Christians to whom he had ministered on earth (see a similar situation in 2 Corinthians 1:14).

In addition, Paul says in 1 Corinthians 13:12, "For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known" (NKJ). That last phrase, "I shall know just as I also am known" would indicate that we shall know others as well as be known by others.
